Network Basics
The IEEE (Institute of Electrical and Electronic Engineers) project 802 decided to use Ethernet
version 2 as the basis for its new CSMA/CD network standard. By enhancing the DEC, Intel and
Xerox Ethernet 2 design, they produced the IEEE 802.3 specification, which is now the standard
format for Ethernet based systems.
The name 10Base indicates a signaling speed of 10 million bits per second with a base band
signaling scheme.
• 10BaseT 10Mbs Ethernet running over twisted pair cable 100 meter Max..
• 100BaseT 100Mbs Ethernet running over twisted pair cable 100 meter Max.
Other 802.x standards
The IEEE committee are also responsible for other 802 networking specifications:
• 802.1, this group produced an overview of the work of the project and defined the LAN
reference model.
• 802.2, this describes the logical link control services used in all IEEE specified LANs.
• 802.3, describes Ethernet based networks.
• 802.3z, describes the Gigabit Ethernet format.
• 802.4, describes networks using a token-passing bus.
• 802.5, describes networks using a token-passing ring.
• 802.6, specifications for a metropolitan area network.
• 802.7, this group advised other working groups on issues relating to broadband
transmission.
• 802.8, this group are the technical advisory group for FDDI and fibre optic.
• 802.9, this group explores integrated data and voice networks.
• 802.11, group for wireless Ethernet
